PAEONIA

There are 30 or so species in this genus of beautiful herbaceous perennials and deciduous shrubs, all native to temperate parts of the Northern Hemisphere. They have long-lived, rather woody rootstocks and stems, and bod foliage. Leaves are dark green to blue-green, usually toothed or lobed, and are sometime maroon or red-tinged. The large flowers are usually erect and solitary, cup- or saucer-shaped, and have brightly colored petals surrounding a mass of short stamens. Petals may be white, yellow, or shades of pink, sometimes flushed red at the center, and stamens are mostly white or yellow. The genus name goes back to Ancient Greek times and refers to the supposed medicinal properties of the species.


CULTIVATION


Paeonia species can urvive in cold climates as long as they have protection from early spring frosts, strong winds, and hot sun. They prefer full or slightly filtered sunlight with cool moist soil. Propagate from seed or by division.


Top Tip


Paeonia plants are susceptible to gray mold, which rots leaf bases, stems, and buds. Spray affected plants with a fungicide and make sure the soil is well drained.
